Neutrons revive Heisenberg's first take on uncertaintyPhysics World Share Physicists in Austria and Japan are the first to measure two physical quantities that were used in 1927 by Werner Heisenberg in an early formulation of quantum mechanics – but then abandoned because the terms did not seem to agree with the rapidly-evolving theory. The neutron experiment verifies a 2003 reformulation of Heisenberg's famous uncertainty principle that reintroduces the concepts of error and disturbance.More

Nanotube bundles could boost solar cellsPhysics World Share Thin-film solar cells could be made far more efficient with the addition of bundles of carbon nanotubes. So say researchers at the Los Alamos National Laboratory, who have shown that the bundles can be used to adeptly perform the two important steps for generating an electric current. It is first time this has been demonstrated in a single thin-film photovoltaic material. Read the associated APS Physics Focus story.More

Early supermassive black holes could grow it alonePhysics World Share Astronomers know that supermassive black holes at the centers of galaxies existed in the early universe, but how these objects managed to accumulate such heft in a short cosmological timespan is a mystery. Now, a team of researchers in Germany and the U.S. has used a humongous computer simulation to show that cold streams of gas from outside a young galaxy could have fed its central black hole fast enough for the hole to grow rapidly.

Planes expected to reroute following massive solar eruptionFox News Share An immense blast of plasma spewed from the sun led to the strongest radiation storm bombarding our planet since 2005, and a rare warning from the National Oceanic and Atmospheric Agency - and even a plan to redirect certain high-flying airplanes.More

Weaker sun will not delay global warmingReuters Share A weaker sun over the next 90 years is not likely to significantly delay a rise in global temperature caused by greenhouse gases, a report said. The study, by Britain's Meteorological Office and the university of Reading, found that the Sun's output would decrease up until 2100 but this would only lead to a fall in global temperatures of 0.08 degrees Celsius.More

Physicists hope to catch neutrons in the act of jumping from our universe to anotherPopular Science Share The notion of multiple universes is one that cosmologists like to theorize about but generally don't relish proving, mainly because doing so would be very difficult. But a team of researchers that showed a few years ago how matter might travel between our universe and others now think they ought to be able to observe this phenomenon in action using existing technology, lending credence to the multiverse theory. All they need is a neutron bottle, some neutrons, and a year. More
